HOSTING APPARATUS.

Application led January 19, 1924.

To all whom t may concern.'

Be it known that I, TALTER F. Gunnar.- cAN, a citizen of the United States, residing` at Great Neck, in the county of Nassau and State of New York, have invented a certain new and useful Improvement in Hoisting Apparatus, of which the following is a specilication.

The invention relates to mechanism for hoisting ashcans and other loads from a cellar floor to the sidewalk and is designed more particularlyT for service in buildings in which it is necessary to transfer such loads laterally through a cellar window to the sidewalk level.

The object of the invention is to provide simple, easily installed and operated means by which such transfer may be conveniently accomplished. A further object is to provide means for reliably supporting the load in the window opening, above the sill, and presenting it in position for easy removal without damaging the sill or other portions of the window frame.

The invention consists in certain novel features and details of construction and arrangement by which the above and other objects are attained, to be hereinafter described and claimed.

rlhe accompanying drawings form a part of this specification and show an approved form yof the invention.

Figure 1 is a vertical section through a portion of a cellar, showing the hoisting apparatus in elevation.

Figure 2 is a corresponding plan view, partly in horizontal section taken on the line 2-2 in Figure 1.

The remaining figures are on a larger scale and show details of certain portions of the hoisting apparatus.

Figure 3 is a vertical section of the cranestandard, partly in elevation.

Figures l and 5 are horizontal sections taken on the lines l-llrand 5 5 respectively in Figure 3.

Similar reference numerals indicate .the same parts in all the figures.

The cellar floor is marked 10, and the window opening in the wall of the cellar, above the sidewalk level, is marked 11. On the tloor 10 in proper relation to the window opening is mounted a vertical post 12, preferably tubular, resting upon a foot 13 and having a bracket 14 attached to the adjacent Serial No. 687,168.

"wall 15 to aid in supporting it in the upright position. ln the upper end of the post is inserted a vflanged plug 1G having` a raceway in its upper face for a circular seriesof antifriction balls 17.

rEhe upper portion of the post 12, above the bracket orbrace 14, is inclosed loosely by a tube 18 of larger diameter having its upper end closed by a cap 19 on the under face of which is a hardened plate 2O resting 65 upon the balls 17 and with the latter and the plug 16, serving as an antifriction step or bearing supporting the tube 18 and permitting its easy partial rotation upon and relatively to the post 12. The lower end of the tube 18 is provided with a collar 21 incircling the post and serving to maintain the tube in position thereon.

rlhe post 12 and tube 18 form the standard for the laterally extended crane arm 22 lixed 75 upon the tube and reinforced by a brace 28 extending from a fixed collar 241 on the tube to a point at the midlength of the arm. Brackets 25 loosely inclosing the tube and attached to the wall 15 `maintain the tube 80 and its inclosed post in the vertical position.

Fixedly mounted on the tube 18^near its lower end is a windlass, only partially represented, comprising a freine 26 in which is a gearwheel 27 on a shaft 28 which also car- S5 ries the winding drum 29, indicated in dotted lines in Figure 1. The gearwheel and drum are rotated by a pinion 30 on a shaft 31 in mesh with the gearwheel and turned by a crank 32 on the shaft 31. rlhis wind- 90 ing mechanism may be of any approved type mounted to rotate with the tube 18, and may be understood to be provided with a brake mechanism and holding pawl and other equipments as usual.

From the drum 29'the hoisting cable 33 extends vertically to and over the pulleys 34 and in the crane arm 22, and itsv depending end carries a hook 36 adapted to engage the load to be hoisted, shown as an l ashcan 37. By turning the crank 32 the can may be raised or lowered, and by lateral pressure on the frame 2G in one direction or the other, the windlass, tubev 18, and crane arm 22 may be swung correspondl ingly, the tube 18 partially rotating upon the fixed post 12 to permit such movements. The crane arm lies a little lower than the lintel or top of the window opening 11.

0n the tube 18 and loosely inelosing it 110 is a sleeve 38 rotatably supported at its lower end on the lowermost bracket and having at its midheight an annular swell 39 the interior of which provides an annular recess 40 in which is received the convolutions of a helical expansion spring 41, one end of which is engaged in a radial hole in the tube 18, and the other end lies against one en-l of a wide peripheral slet or opening 44 in the swell 39. At the top of the sleeve 38 is fixed a radial bracket carrying a shelf or platform 46 supported at a height slightly above the window sill of the opening 11.

The crane arm 22 and bracket 45` both extend radially but at an angle to each other normally, due to the action of the spring 41 the tension of which is exerted to rotate or partially turn the tube 18 and sleeve 23S relatively to each other, the extent of such movement beine' determined by a stop pin 4'? set in the tube 18 and extending radially into a peripheral slot 48 in the swell 39 of the sleeve 38. Such expansive force holds the bracket 45 and crane arm 22 normally in the angular positions shown by vthe dotted lines at A in Figure 2 and by the full lines in the same figure, but such engagement is yielding in the direction to bring the crane arm 22 and bracket 45 into vertical alinement by arresting the movement of the bracket and continuing the movement of the arm in such direction.

The operation is as follows The crane arm 22 and platform 46 beine" in the position shown at A in Figure 1 in the dotted lines, the hook 36 is lowered and attached. to the can 37 g the latter is then raised to a height slightly above the level of the platform 46, seeFigure 1, by the rotation of the hoisting drum 29, and held thus suspended, then, by pressure of the operator against the frame 26, the tube 18 with its crane arm 22 and the sleeve 38 with its platform 46 are swung as one toward the window opening 11 but at an angle toeach other until the bracket 45 strikes the jamb or side of the window opening and is arrested; by continuing the rotation of the tube 18 the crane arm 22 overtakes the platform, against the tension of the spring 41, and with its load is swung over the plat form 46 within the Window opening, as indicated by the dot-ted lines at B in Figure 2. While still maintaining the pressure and holding the crane arm in this position, the can is lowered upon the plaform and is supported thereby, and on slacking the cable 33, or by disengaging the hook 36 from the can, with the aid of an assistant on the sidewalk, and relaxing the pressure on the frame 26, the tube 18 is partially rotated in the reverse direction relatively to the sleeve by the expansion of the spring 41, thus automatically moving the crane arm 22 back to the position shown in full lines in Figure 2, leaving the can deposited on the platform 46 ready for removal. An empty can from the sidewalk may be placed on the platform, the hook engaged therewith, and the whole swung inwardly with the empty can presented in position for lowering.

It will be noted that the operation may.' be performed by a single operator who ma)Y raise the can, deposit it on the platform and then ascend to the sidewalk and remove it. Also that the platform protects the window sill and offers a substantial and level support for the can while awaiting removal, and that the apparatus may be swung inwardly clear of the window open ing out of the path of a window sash in opening or closing the latter.

The apparatus is especially adapted for service in buildings having no sidewalk hoistway, in which the cans are to be delivered through a side window, and is designed to be easily installed in such situations.
